The film opens in the Forbidden City in 1887, where Chon Lin (Fann Wong) is drinking tea with her father, the Keeper of the Imperial Seal of China. She tells him her brother, Chon Wang (Jackie Chan), is doing well as a sheriff in Carson City, Nevada, United States, but her father replies that her brother is dead to him. At that moment, Lord Nelson Rathbone (Aidan Gillen), leads a band of Boxers into the city, who attack the Keeper. Rathbone stabs him and leaves with the seal. As he lies dying, he gives Lin a puzzle box and a letter to Chon Wang.

Back in the Wild West, Chon Wang is doing well as sheriff, having captured an impressive array of fugitives. His deputy is relaxing with a book called “Roy O’Bannon Vs. The Mummy”, a highly fictionalized account of the events of the first film that now portrays Wang’s “Shanghai Kid” as a cowardly sidekick.

Wang receives a parcel, which contains the puzzle box and Lin’s letter, telling him his father is dead and that she has tracked the murderer to London.

Chon Wang travels to New York City to find his old partner Roy O’Bannon (Owen Wilson), needing his share of the gold left over from the first film to buy his ticket. Roy has left his brief stint in law enforcement, broken off his romance with Falling Leaves, spent most of the gold investing in the Zeppelin, and is now a hotel waiter and part-time gigolo. After they attempt prostitution to pay for a trip to England, the Mayor of New York arrives in search of his daughters, Roy’s latest clients. Chon Wang fights off a number of New York police officers, and he and Roy ship themselves to London in a crate. On the way, Wang tells Roy about his father, and Roy swears an oath to help reclaim the seal.

…

Roy and Wang are knighted, as is Artie, whose full name is now Sir Arthur Conan Doyle. Artie decides to become a writer, his stories revolving around his deductive reasoning technique, and asks Roy if he can use the “Sherlock Holmes” name. Roy and Lin kiss, and Roy proposes that he and Wang go to Hollywood to get in on the ground floor with motion pictures. They roll off in a buggy, with Charlie stowed away. Wang also manages to open the box his father sent him, finding a message inside reminding him of the importance of family.

A warlord (Jet Li) in Ancient China conquers his enemies and becomes The First Emperor Of China, known as The Dragon Emperor Han or Emperor Han. As his first act as Emperor, he orders the construction of The Great Wall Of China, burying his former enemies beneath it and cursing them to hold it up for all eternity. The Emperor orders a witch, Zi Yuan (Michelle Yeoh), to search for the secret to immortality with the aid of The Emperor’s right-hand-man, General Ming Guo (Russell Wong). Zi Yuan and Ming fall in love, angering the Emperor who desired Zi Yuan for himself. After Zi Yuan supposedly casts the immortality spell on The Emperor in Sanskrit, a language he does not understand, he has Ming drawn and quartered and wounds Zi Yuan. She then reveals that she had foreseen this and has in fact cursed The Emperor and his army, who are encased in clay, becoming The Terracotta Army, permitting Zi Yuan to escape.

In 1946, 13 years after the events of The Mummy Returns, the now-Americanized Alex O’Connell (Ford), son to Rick (Brendan Fraser) and Evelyn (Maria Bello), locates Emperor Han’s Tomb with the financial backing of Professor Roger Wilson (David Calder), an archaeology professor. Alex is attacked by an unknown woman, but succeeds in bringing The Emperor’s coffin to Shanghai. Meanwhile, the British government entrusts The O’Connells to take The Eye Of Shangri-La back to China as a good faith gesture to The Chinese. It is revealed that Wilson is in league with a Communist paramilitary group led by General Yang (Anthony Wong Chau-Sang) and his second-in-command, Choi (Meng), who see The Emperor as the only one who can bring order and greatness back to China. The mysterious woman from the tomb attacks the mummified Emperor in his coffin, which turns out to be a decoy. By accident, the magical fluid within The Eye lands on the statue of The Emperor, which is revealed to be the actual Emperor’s body. He is quickly brought back to life, although he remains trapped in his Terracotta form. Han accepts the service of Choi and Yang but kills Wilson. The woman from the excavation site tries to kill The Emperor with a magical dagger, the only weapon that can kill him, but is unsuccessful in killing The Emperor.

…

The O’Connells return to Shanghai, where Alex and Lin fall in love. Jonathan decides to move to Peru with the Eye of Shangri-La, which he had stolen himself, as there are no mummies in Peru. However, an ending comment appears, explaining that shortly after his arrival, mummies were soon discovered in Peru.

The story begins two years from where the previous film ended, and Peter Parker is finding his double life increasingly difficult. Precariously struggling to balance his crime-fighting duties with the demands of his normal life, Peter often finds his personal life taking a back seat. He loses a job, faces financial difficulties, and struggles to maintain his physics studies at Columbia University. Moreover, he has become estranged from both love interest Mary Jane and best friend Harry Osborn, and Aunt May is threatened with foreclosure.

Harry, now head of Oscorp’s research division, has invested in the research of brilliant scientist Otto Octavius, Peter’s idol. To perform a sustained fusion experiment, Octavius has developed a set of artificially intelligent mechanical arms, which are impervious to heat and magnetism. Though the experiment overloads and becomes unstable, Dr. Octavius refuses to halt it, with devastating results: his wife is killed; the neural inhibitor chip which enabled him to control the arms is destroyed; and the arms are fused to his spine. Unconscious, he is taken to a hospital to have the tentacles removed, but the tentacles kill the surgeons, and he escapes. Uncontrolled, the tentacles begin to influence Octavius’ mind, playing on his vanity and ego, and he decides he must complete his experiment at any cost. J. Jonah Jameson names him Doctor Octopus or “Doc Ock.” Doc Ock attempts to rob a bank where Peter Parker and his Aunt May happen to be present. After a short glitch in his powers, Spider-Man manages to recover shortly after that and soon the two take their fight outside the bank, but Doc Ock takes Aunt May as a hostage. When Spider-Man rescues her, she revises her former opinion of him and realizes that he is a hero.

…

Across town, Harry has visions of his father, the late Norman Osborn, in a hanging mirror. The illusion demands that his son kill Peter Parker to avenge his death. Harry refuses and hurls a dagger at the mirror, shattering it and revealing a secret room, containing the Green Goblin’s war gear. At the end of the film, Mary Jane leaves her wedding and finds Peter in his apartment, telling him that she has decided to be with him â€“ despite the risks. She persuades Peter to finally let her in while accepting the need of his vows by letting him respond to a sudden call for help. She looks on in uncertainty as Spider-Man swings away.
